BEFORE PERFORMING ANY
ELECTRICAL WORK, READ THESE
REGULATIONS
1. All wiring must comply with local and national
electrical codes, regulations and must be
installed by a licensed electrician.
2. All electrical connections must be made
according to the Electrical Connection Diagram
located on the panels of the indoor and outdoor
units.
3. If there is a serious safety issue with the power
supply, stop work immediately. Explain your
reasoning to the client, and refuse to install the
unit until the safety issue is properly resolved.
4. Power voltage should be within 90-110% of
rated voltage. Insuf cient power supply can
cause malfunction, electrical shock, or re.
5. If connecting power to xed wiring, install a
surge protector and main power switch with
a capacity of 1.5 times the maximum current
of the unit.
6. If connecting power to xed wiring, a switch
or circuit breaker that disconnects all poles and
has a contact separation of at least 1/8in (3mm)
must be incorporated in the xed wiring. The
quali ed technician must use an approved
circuit breaker or switch.
7. Only connect the unit to an individual branch
circuit outlet. Do not connect another
appliance to that outlet.
8. Make sure to properly ground the air conditioner.
9. Every wire must be rmly connected. Loose
wiring can cause the terminal to overheat,
resulting in product malfunction and possible re.
Do not let wires touch or rest against refrigerant
10.
tubing, the compressor, or any moving parts
within the unit.
If the unit has an auxiliary electric heater, it must
11.
be installed at least 1 meter (40in) away from
any combustible materials.
12.
To avoid getting an electric shock, never touch
the electrical components soon after the power
supply has been turned off. After turning off
the power, always wait 10 minutes or more
before you touch the electrical components.
WARNING
BEFORE PERFORMING ANY ELECTRICAL
OR WIRING WORK, TURN OFF THE
MAIN POWER TO THE SYSTEM.
Step 6: Connect signal cable
The signal cable enables communication between
the indoor and outdoor units. You must first
choose the right cable size before preparing it for
connection.

CHOOSE THE RIGHT CABLE SIZE
The size of the power supply cable, signal
cable, fuse, and switch needed is determined
by the maximum current of the unit. The
maximum current is indicated on the nameplate
located on the side panel of the unit. Refer to
this nameplate to choose the right cable, fuse,
or switch.
